Bennie Schut commented on HIVE-1539: ------------------------------------ thanks Paul, I didn't notice that yet so in theory it shouldn't be the cause. However after synchronizing the metastore client I never saw this problem again where I used to see this problem every day. Strange issue. I'll see if I can create something reproducible but that might be tricky for this type of problem. > Concurrent metastore threading problem > --------------------------------------- > > Key: HIVE-1539 > URL: https://issues.apache.org/jira/browse/HIVE-1539 > Project: Hadoop Hive > Issue Type: Bug > Components: Metastore > Affects Versions: 0.7.0 > Reporter: Bennie Schut > Assignee: Bennie Schut > Attachments: thread_dump_hanging.txt > > > When running hive as a service and running a high number of queries > concurrently I end up with multiple threads running at 100% cpu without any > progress. > Looking at these threads I notice this thread(484e): > at > org.apache.hadoop.hive.metastore.ObjectStore.getMTable(ObjectStore.java:598) > But on a different thread(63a2): > at > org.apache.hadoop.hive.metastore.model.MStorageDescriptor.jdoReplaceField(MStorageDescriptor.java) -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
